Title: Non-thermally emissive electrodes
IPC: H01J1/30
Filed: 1973-03-23
Abstract: 1413552 Electrode materials and processing PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 March 1973 [27 March 1972 (2)] 14094/73 Heading H1D In a method of manufacturing a non-thermally emitting electrode, for an electric discharge tube, activated by a thin layer of alkali metal or alkaline earth metal, the activation material is diffused into the electrode material prior to mounting the electrode in the tube, after which the electrode is mounted in the tube and the activation material then provided in a monoatomic layer on the electrode surface by segregation resulting from heating. Heating may be by induction or radiation. The electrode and activation materials are preferably such that the latter is absorbed interstitially, and also in a supersaturated condition. The activation material can be incorporated by vapour deposition followed by thermal diffusion, or the electrode may be covered with a suspension of the activation material in a neutral liquid which is evaporated or may be dipped in a non-reactive metal bath in which the activation material is suspended, followed by indiffusion. Indiffusion may be enhanced by an electric field. Any thick layer formed at the surface prior to mounting may be removed by polishing mechanically, chemically or electrochemically, and after mounting may be cleaned by ion bombardment. Fission, especially of a single crystal, may provide a clean surface. Indiffusion may be continued until the concentration near the surface is 1 to 10<SP>4</SP> p.p.m. Surface segregation times are preferably such that according to the formula t # (N/C)<SP>2</SP> x (1/D), the time is <10<SP>5</SP> sees., where N is the number of atoms/cm.<SP>2</SP> in a monolayer, C is the initial conc. near the surface, and D is the diffusion coefficient. Electrode materials may be metals but preferably P-type semi-conductors, especially III-V compounds. The electrode may be amorphous, polycrystalline or monocrystalline, and field emission, secondary and photoemission are specified. In an example, a Si crystal surface is covered with a suspension of metallic Li in paraffin oil, the oil evaporated, the crystal heated to 400‹ C., in diffusion of Li in the Si occurring, the operation repeated three times over 24 hours. The Li conc. is 1 p.p.m. The Si body is placed in a 10<SP>-10</SP> to 10<SP>-9</SP> torr vacuum, a (III) crystal face formed by fission, and the crystal heated to 200‹ C. to form the Li monolayer. The Si was P-type with 10<SP>14</SP> atoms of B/c.c. GaP with Rb, K or Cs as a secondary emitting electrode is mentioned. With an initial conc. of 10<SP>18</SP> atoms of K/c.c., a monolayer is produced in 1 hour at 300‹ C.

Title: Improvements in or relating to hydraulic clutches or couplings
IPC: F16D31/02
Filed: 1940-09-23
Abstract: 542,737. Hydraulic clutches. HYLAND, C. Sept. 23, 1940, No. 14449. [Class 69 (ii)] In a hydraulic coupling or clutch comprising a radial cylinder pump having its cylinder block 1 carried by a driving shaft 2 and its pistons 13, 14 operated or controlled by an eccentric 15 carried by a rotary pump casing 3 associated with a driven shaft, the pump is initially loaded by spring-loaded cylinder outlet valves 21, which on excessive loading or resistance, open to allow the excess pressure oil to be delivered into a conduit or duct 20 common to all the cylinder inlet valves and from which such oil can be drawn into the cylinders during the return stroke of their pistons. The pump cylinders are either main, 11, or auxiliary, 12, and their pistons 13, 14 are actuated by the eccentric 15. A valve chamber 19 is associated with each pump cylinder, those for the main cylinders having pressure release valves 21 arranged co-axially with lightly loaded inlet valves 22 leading from the conduit 20 and the chambers for the auxiliary cylinders, outlet and inlet valves 23, 24. Normally the whole clutch rotates solidly but if excessive torque creates excessive pressure in a main cylinder 11, its valve 21 opens and pressure oil is delivered to the conduit 20 to enter the other cylinders through their inlet valves. As long as this continues, the clutch slips and the auxiliary pistons pump oil from a sump 7 to the conduit 20, slightly increasing the pressure therein, excluding air therefrom and promoting circulation of the oil to dissipate the heat generated. The valve chambers connect with the sump 7 through a sliding valve member 29 in the driving shaft 2 and when the valve member 29 is moved manually to its extreme end position, an annular port in the member puts all the main cylinders into communication with each other to render the clutch inoperative.

Patent GB-651434-A (GB)
Title: Improvements in or relating to the production of regenerated cellulose sheet wrapping materials
Inventor: BERRY WILLIAM
IPC: C08J7/06
Filed: 1948-05-28
Abstract: Sheet wrapping material, suitable for the wrapping of ferrous metal articles, comprises flexible regenerated cellulose sheet or film wherein there is incorporated a corrosion-restraining organic compound comprising a water - soluble orthophthalate having the formula C6H4(COOR1)2 or C6H4(COO)2R11, wherein R1 represents an atom of an alkali metal or the ammonium group (NH4), and R11 represents an atom of an alkaline earth metal or of magnesium.  The corrosion inhibitor may be disodium orthophthalate or magnesium orthophthalate. Dipotassium, diammonium, and calcium orthophthalates are said to be less satisfactory.  The proportion of orthophthalate should preferably be at least 0.5 per cent, e.g. 4-8 per cent (optimum about 5 per cent) based on the combined weights of cellulose and any softening agent which may be present.  The softening agent may be glycerine (e.g. 10-25 per cent by weight or more based on the combined weights of cellulose and glycerine).  Urea, sometimes employed as a softening agent of regenerated cellulose, is said to promote corrosion and hence to be unsatisfactory.  The corrosion inhibitor may be introduced into the sheet after the latter has been formed by impregnating the sheet with an aqueous solution containing at least about 0.17 per cent of the inhibitor.  The solution may also contain a softening agent.  The regenerated cellulose sheet is preferably impregnated while in the gel state.  Alternatively, the inhibitor may be introduced into the sheet by spraying the latter, after the application of the softening agent, with a fine spray of an aqueous solution of the inhibitor.  In an example dried softened regenerated cellulose film is freed from softening agent by soaking in water, and the wet film is impregnated by immersion for 30 seconds at 60 DEG  C. in an aqueous solution containing 6.0 per cent of glycerine and 4.0 per cent of disodium orthophthalate. The film is then transferred to a polished plate, excess liquid removed from the surface by means of a rubber squeegee, and the film dried in a current of warm air.  Comparative rusting tests are described using as test pieces polished mild steel plates wrapped in regenerated cellulose films with and without orthophthalates.

Title: Improvements in devices for damping flames from the exhaust pipes of internal combustion engines
IPC: F01N13/20
Filed: 1943-09-06
Abstract: 568,140. Treating exhaust. DANINOS, J. C. Sept. 6, 1943, No. 14576. [Class 7 (ii)] [Also in Group XXXIII] A device for quenching the flame of the exhaust comprises a circular inlet 10 leading to a fish-tail outlet 12 formed with corrugations or flutings 14, the device being bent once near its outlet end in a plane perpendicular thereto. The hot gases pile up in the upper part of the bend and the outer layer is cooled by air flowing thereover before it expands on leaving the outlet to form a thin, cool, protective layer which keeps the hot gases from contacting with the surrounding air and thereby prevents the formation of flame. To avoid turbulence, the inner surface of the device is smooth and its intermediate cross-section has the shape shown in Fig. 4. The corrugations may be provided with cooling fins and additional corrugations be formed on the lower face of the device. The corrugations may be strengthened by a band across their outer ends or the material there may be of double thickness. As shown in Fig. 13, the device is formed in two halves welded together and the corrugations are strengthened by a corrugated strip 26 backed by a plain strip 30.
